I have two FIXED frequency monitors that I have been unable to service. Mostly
due to lack of schematics.
1. 1989 version "MaxPC" brand built by Toshiba 21".
Remove the plastic cover and it is encased in metal all around. EMI
protection? Weighs a ton. One day many years ago I backed up monitor stand
until the vert adjust screwdrive left in back crushed the vert adj pot to
smithereens. I got a horz bright white line. I took the pieces and took a
guess at value and discovered somthing else died also. Freq is about 48KHz.
2. SUN 20D10 monitor. has a daughter card with a bunch of ittty bitty caps on
it that are reputed to have bad ESR that is causing the bad UNadjustable
pincoushion. Daughtercard seems to be one of those parts hung in midair and the
mother board assembled around it, THEN the montor assembled around THAT! Freq
is about 70-110 Khz
I have boxes still if you want them shipped. Location is Warminster PA (near
Philly) Assume 80lbs and they might be less at weigh in.
